turbotyla Posted November 17, 2008 Share Posted November 17, 2008 Ok i know you guys are getting tired of hearing me ask petty little questions but i am trying to get my little mj on the road and i have did the best to my knowledge. But some things are stumping me and any other angle at the problem is much appriciated I fixed all the vacuum lines i could find and blocked off a few from what some ppl told me on the last post. and full tune up etc etc.... But when my truck warms up only when its starting to get warm. a loud whining comes from back of the motor somewhere i cannot find it and the truck begins to idle up around 2000 rpm I cannot find a vacuum line that is torn i have taken off replaced and played with every vacuum connection trying to find it. tried a few other things to no avail If anybody has had this problem before please help me out. or if anybody has any ideas what could be doing it Any help is much appriciated. i want this to be my winter truck and i sold my other means of transportation so i am kinda stuck. let me know.. thanks guys Link to comment Share on other sites More sharing options...
BLHTAZ Posted November 17, 2008 Share Posted November 17, 2008 Sounds like you may have removed or blocked something that you shouldn't have. I don't believe that there is anything that you can remove or block off on these so it is likely that you did something that needs to be replaced / repaired. I have been all over mine and the only thing I can think that may be able to be done without is the EGR... :???: Link to comment Share on other sites More sharing options...
turbotyla Posted November 17, 2008 Author Share Posted November 17, 2008 well that is all i block off was the egr and even before i did this my truck idled really high and whines. it stops whining when i give it gas. so i think its vacuum related for that reason Maybe an intake leak ? idk i need help Link to comment Share on other sites More sharing options...
JeepcoMJ Posted November 17, 2008 Share Posted November 17, 2008 how does your brake pedal feel? brake booster leak perhaps? vacuum canister leak? Link to comment Share on other sites More sharing options...
BLHTAZ Posted November 17, 2008 Share Posted November 17, 2008 It definitely sounds vacuum related and an intake leak could do it for sure, but that's a tough one to diagnose. I have heard of a few people finding that they have a loose intake manifold bolt that was allowing a leak that when tightened, the idle problem stopped.
